My Sign: Brief banner + Earthman [Shabby Cardstock] backup deck when no equipped — TDD

User-reported gap on /billboard/my-sign/ — admin user's only deck was in-use as `TableSeat.deck_variant` in another room (Wonderbeard) → `equipped_deck` cleared → previous my-sign template showed "Equip a card deck first…" w. no actionable next step. User scoped fix: don't force equip, just nudge via a Brief banner "Look!—no deck is equipped. Navigate to the Game Kit to equip one (FYI) or (NVM) proceed with the Earthman [Shabby Cardstock] deck.", title "Default deck warning". NVM dismisses + picker proceeds against an Earthman card pile labeled in-copy as the temporary backup; FYI links to /gameboard/ (Game Kit equip). User-modified line text in template: "Paperboard" → "Cardstock" mid-session ; **helper fallback** (epic/models.py): `personal_sig_cards(user)` now falls back to `DeckVariant.objects.filter(slug='earthman').first()` when `user.equipped_deck` is None — same 16-or-18 card pile, just sourced from the canonical Earthman deck rather than the empty FK. No new DeckVariant row needed; "Shabby Cardstock" is purely UX framing (cards are the same TarotCard records the room sig-select uses). Preserves the existing helper signature so no callers had to change ; **view + template** (billboard/views.py + my_sign.html): view passes `no_equipped_deck` + `show_backup_intro_banner` flags. Template removes the old `{% if not equipped_deck %}` forced-equip branch — picker now renders unconditionally w. cards from the backup helper when no deck is equipped. Brief banner fires via `Brief.showBanner({...})` on DOMContentLoaded when `show_backup_intro_banner` is true — gets h2-overlay positioning + NVM behavior + portal styling for free (per [[sprint-baltimorean-note-unlock-may18]] portrait h2 measurement in note.js's `_alignToH2`). Added `<script src="note.js">` to my_sign.html since the page didn't load it before. Post-render JS tags the Brief w. a `.my-sign-intro-banner` class so FTs (and any future my-sign-specific styling) can distinguish this nudge from other Briefs on the page ; **TDD trail** — 4 new FTs in `MySignBackupDeckTest` (test_bill_my_sign.py): T1 banner renders w. "Default deck warning" title + "no deck is equipped" + "Shabby Cardstock" copy + both action btns visible; T2 picker still populates 16 cards from backup; T3 NVM click removes the banner from the DOM; T4 FYI href ends w. /gameboard/. Initial reds (`NoSuchElementException` on all 4) confirmed before implementation. Plus 1 new IT in `PersonalSigCardsTest` pinning the helper fallback (16 cards w. all `c.deck_variant.slug == "earthman"`) ; pre-existing change picked up: `static_src/scss/rootvars.scss` (user-modified mid-session) ; 1020 IT/UT green; 7 FTs green (3 picker happy-path + 4 backup deck) in 56s. Sprint 4a-follow complete — primary deferral from Sprint 4a (deck-source fallback UX) now landed. Unblocks Sprint 4b (My Sea gating w. --terUser link to /billboard/my-sign/ when no sig set)
